between the thickness of the main portion 32 and the fixing
protrusions 34 so as to provide smooth transition between the main
portion 32 and the fixing portions 34 without jeopardizing the
interior rigidity thereof. The distance between the contacting
portions 23 of the internal terminals 27 and the main portion 32 is
greater than the distance between the contacting portions 23 of the
grounding terminals 26 and the inclining portions 38 increasing
withstanding of voltage. In this embodiment, the main portion 32 is
thinned compared with the inclining portions 38 via a
pressing/forging operation for increasing density thereof so as to
assure the required rigidity thereof even if the thickness
dimension is less than that of the inclining portions 38. It is
noted that in this embodiment the main portion 32 is essentially
located among the front fixing portions 34, the inclining portions
on two sides, and the associated supporting portion 31 and
connecting portions 33 in a protectively surrounded manner, all of
which have the larger thickness than the main portion 32. This is
also another reason why the main portion 32 is allowed to occupy
most portions of the tongue portion 15 without improperly
jeopardizing the strength of the tongue portion 15. Notably, the
main portion 32 forms a plurality of through holes (not labeled)
for receiving material of the third insulator 13 therein. Another
feature of the invention is to have the shielding plate 3 forms a
space (not labeled) in a front end region, which is surrounded by
the pair of fixing protrusions 34 and the front edge of the main
portion 32, and is adapted to be filled with material of the third
insulator 13 in a later time as well as the aforementioned through
holes in the main portion 32.
While a preferred embodiment in accordance with the present
disclosure has been shown and described, equivalent modifications
and changes known to persons skilled in the art according to the
spirit of the present disclosure are considered within the scope of
the present disclosure as described in the appended claims.
